Sorry for not being clearer. Yes, my understanding is that it's permitted.
OP, are you resident in Haringey?
Their permit is a good idea because it gives access to bays which would normally not be available to BB holders.
Why do they have this permit?
Simples. While a BB cannot be virtual, this permit can. The council's concern is the misuse/theft of BBs and therefore they've not allowed BB parking but have allowed BB permit parking. Very sensible and a bonus for resident BB holders.
But it extends to residents, not visitors, hence my question.
